A smoother surface would also tend to reduce friction. This may not be 100% correct you may not want a super fine finish as it may not let your ring & pinion retain the lube the parts don't like to run dry.

I've been getting gears done for a few years and they appear to be lasting longer. I was not in a position to do back-to-back tests with the "Finished" surface treatment, but others I know have had positive responses. It would stand to reason that a highly polished surface would at least have less resistance moving through oil over OEM machined and coated surfaces. A smoother surface would also tend to reduce friction. I wouldn't be wasting my time on it if I didn't think it was beneficial.
